Specification of Letters Patent.

Patented Mar. 21, 1916.

Application filed August 20, 1914. Serial No. 857,675.

To all whom it may concern: I

Be it known that I, JAMES HARRY Lnvrs, a subject of the King of Great Britain, and

resident of Watertown, county .of. Middletic materials such as cement, glass, porcelain and the like and the object of the invention is to provide an improved .table' or' bench which will be durable, comparatively inexpensive and which may be constructed in sections readily transferable, and easily assembled.

A further object of the invention is to provide a bench especially adapted for green houses which may be readily dismantled either in whole or in part.

Other objects of the invention will more fully'appear from the following description and the accompanying drawings and will beparticularly pointed out i in the annexed claims.

In the drawings, Figure 1 is a plan view of a portion of a table embodying my invention, Fig. 2 is a vertical sectional view onlines 22 Fig. 1, Fig. 3 is a vertical sec. tional view on lines 3-3 Fig. l, and, Figs. 4, 5, and 6 are respectively views of the side member, the longitudinally extending central supporting member and one of the transversely disposed supporting members.

In view of the high humidity which is always present in green-houses it is desirable that the tables be constructed of some material which will not absorb water and be warped thereby or become .disintegrated by the action of the highly humid atmosphere.

It is frequently desirable to transfer the table from one part of the green-house to another or to remove a portion-of thetable inorder that large plants may be placed in desirable locations.

The present invention contemplates the production of a table in which all of the parts are made from a molded plastic material such as concrete, glass or porcelain and constructed in relatively small sections having their adjacent edges interlocking in such a manner that the table may be dismantled readily but which when assembled will aflord an exceedingly rigid support for plants and like articles.

The preferred form of the invention disclosed herein comprises a series of transverse members 1, supported upon posts 2 located adjacent to the ends of the transverse members, said transverse members being connected by a series of preferably centrally disposed supporting members 3 and slde members 4, 5, disposed on opposite sides of the central members 3 and supported by said central supporting members and by the transverse members 1. In the construction illustrated herein these parts are in substantially a single plane providing a smooth table top upon which to set plants or other articles or which may be utilized to support a bed of earth to grow a solid bed crop of plants.- The table top is desirably provided with an integral flange extending entirely around the table and to accomplish this each of thetransverse pieces is provided at its ends with upstanding beveled flanges 6, and the side members are likewise provided with flanges 7 in alinement with and of equal heightto the flanges 6 upon the transverse member. The transverse members of the end of the table are also desirably provided with a similar flange 8 to complete the continuity of the flange around the table.

In order to providefor supporting the other members of the table top in the manner above described the transverse members 1 are desirably provided with interlocking means desirably in the form of dove tailed recesses 9 extending downwardly from the upper surface thereof and an underlying flange 10 extending beyond the outer ends of the dove-tailed projections intermediate of said recesses. See particularly Fig. 6. As many transverse members as may be desired may :be placed in a series andconnected by thelongitudinally extending central supporting members 3 which desirably are provided at their outer ends with dovetailed tenons 11 adapted to enter the central recess 9 of the transverse members. The longitudinal supporting members are desirably provided with dove-tailed recesses 12 extending downwardly from the upper surface thereof and an underlying flange 13 extending beyond the edges of the upper portion of said centrally disposed member, these flanges being adapted to support the side members 4 which are provided with dove-tailed tenons 14: attheir ends and also at their inner edges to engage respectively the dove-tailed recesses 9 in the transverse members and the recesses 12 in the longitudinally extending supporting members.

The side members may be provided with suitable holes 15 to permit the water to escape from the table top, these holes being desirably arranged in series of three adjacent to the inner edge andtwo adjacent to the outer edge of the side members.

It will be obvious that the table top thus I constructed will be of a very rigid character and yet may be easily dismantled;

. The interlocking members of the various sections may be symmetrically disposed so that any member may be readily replaced if broken or damaged and no especial care required in setting up the table.

7 The table top is desirably supported upon posts 2 located beneath the ends of the several transverse members in the manner above specified and the top ends of the posts .in the transverse supporting members.

plastic material which is capable of being molded into the desired form and possesses sufficient strength for the purposes subserved. For example, the table top may be made of'concrete the side sections being made of a thickness of two inches While the transverse supporting members and the longitudinal supporting members may be of like material and have a thickness of three inches the additional inch in thickness providing for the underlying flange aforesaid. The supporting members and also the side members may if desired be reinforced in any well known manner as by woven wire fabric or other reinforcing material commonly in use. e

The posts are desirably formed of the same material as the table top in order to provide uniformity in appearance but of course may be made of any suitable material.

It is to be understood that the table top and in fact all of its parts may be made of glass or porcelain or other moldable plastic material and that the proportions of the various parts'may be varied in accordance with the requirements of the use to which the table is placed.

While the form oftable disclosed herein 7 is the best embodiment now known to me it is to be understood that variations thereof may be made withinthe meaning and scope of the claims'hereto annexed. 7

It will be obvious that if desired the table legs maybe placed at about the central portion of the transverse members and that a single or a plurality'of members connecting the transversemembers may be used in such" case, the dove-tails and recesses therefor being arranged upon opposite sides of the supporting leg.

. In assembling the members of this'improved table the legs may be secured to thetenons 14 drop into the dove-tailed recesses 9 and 12 respectively of the transverse and longitudinal members.

- Having thus described my inventionwhat I claim as new and desire to secure by Letters Patent is: I

1. A sectional table top constructed of plastic material comprising a series of supporting members having dove tailed recesses extending downwardly from the plane of the upper surface thereof and an underlying supporting flange or ledge, longitudinally extending side members, having dovetail projections adapted to engage the dovetailed recesses of the supporting members,

I the upper surface of the supporting members and side members being in substantially the same plane. 7

2.
